I've had and enjoyed a somewhat modified v4 uBitx for years. Last week we had some area thunderstorms...nothing nearby, but I suspect static buildup on the antenna has zapped my rig. It still receives and appears to operate normally, but has no power out when transmitting on CW or SSB. Even though I added the back-to-back diodes some time back, I immediately checked Q90 and it was bad, so I replaced it, but voltages around that transistor are screwy (Base at 8.6 and Collector and emitter over 7), so something else is wrong and it still won't transmit. When I key it with a nearby receiver on frequency, I do hear it coming on and it modulates, so something in the final transmitter stages I suspect. I plan to check the finals, but with grand kids this weekend I have no time to be on the bench, so I thought I'd post to get any suggestions for when I get back into it. Any thoughts?
